How to Avoid a Climate Disaster

Bill Gates

I've been working for some time now on a book about climate change. In it, I'll share what I've learned from more than a decade of studying climate change with experts and investing in the innovations we'll need to address it. I hope to explain the science in a clear and compelling way. I'll also propose a plan for what we need to do over the next decade and beyond to build the tools that will help us eliminate greenhouse gas emissions while scaling up the powerful solutions we already have. And I'll suggest some concrete steps that individuals, governments, and companies can take to make it happen. The book will be published by Knopf on February 16, 2021.

Osiris-Rex Kisses Bennu

NASA

The NASA Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft briefly touched asteroid Bennu to collect dust and pebbles from the surface for delivery to Earth in 2023.
Bennu is currently more than 320 Gm from Earth. The team needs a few days to check the sample the spacecraft collected. If it is big enough, mission teams will command the spacecraft to head back to Earth in March 2021. Otherwise, they will try again in January.
NASA administrator Jim Bridenstine: "This amazing first for NASA demonstrates how an incredible team from across the country came together and persevered through incredible challenges to expand the boundaries of knowledge. Our industry, academic, and international partners have made it possible to hold a piece of the most ancient solar system in our hands."
OSIRIS-REx principal investigator Dante Lauretta: "After over a decade of planning, the team is overjoyed at the success of today's sampling attempt."

Superluminal Quantum Tunneling

Natalie Wolchover

Quantum tunneling explains various chemical bonds and radioactive decays and how hydrogen nuclei in the Sun can overcome their mutual repulsion and fuse.
Quantum tunneling seems to be superluminal. Thomas Hartman found in 1962 that when a particle tunnels, the trip takes less time than if there were no barrier. Thickening the barrier hardly increases the time it takes for a particle to tunnel across it. With a really thick barrier, particles could hop from one side to the other faster than light in free space.
Quantum theory says that until a particle strikes a detector, its position is uncertain. Picture a wave packet as a bell curve representing the possible locations of a particle, centered at position A and moving toward B. When the wave packet hits a barrier, it splits in two. Most of it reflects, heading back to A. But a smaller peak keeps going toward B. The particle has a chance of registering in a detector at B.
Before it was detected at B, the particle was a two-part probability wave, both reflected and transmitted. Any particle that starts at A and ends at B interacts with the barrier in between, and this interaction occurs in time. After a wave packet hits a barrier, at each instant there's some probability that the particle is inside the barrier.
Clocking the difference between a departure time from A and an arrival time at B doesn't tell you a unique particle's time of flight, because a particle detected at B was anywhere and everywhere in the initial probability distribution. We sum up the probabilities at every instant to derive the average tunneling time.
Aephraim Steinberg and colleagues used the Larmor clock method to gauge how long rubidium atoms took to tunnel through a repulsive laser field. When a charged particle with spin is in a magnetic field, the spin angle precesses. A Larmor clock uses this precession as a clock hand.
The Steinberg team used a laser beam as their barrier and turned on a magnetic field inside it. They then prepared Rb atoms with spins aligned in a particular direction, and sent the atoms drifting toward the barrier. Next, they measured the spin of the atoms that came out the other side. Measuring any individual atom's spin always returns the answer up or down. But repeated measurements reveal how much the angle of the spins precess, on average, while the atoms are inside the barrier, and thus how long they typically spent there.
The Rb atoms spent, on average, 0.61 ms inside the barrier, less time than they would take to go in free space. If you made the barrier really thick, the speedup would let atoms tunnel from one side to the other faster than light.
Superluminal tunneling doesn't allow superluminal signaling because although tunneling through a very thick barrier is very fast, the chance of it happening at all is very low.

AR Quantum disentanglement seems superluminal too: no problem.

Taiwan Faces China Danger

Gideon Rachman

China could take advantage of political confusion in America to make a move on Taiwan.
Global Times editor Hu Xijin: "The only way forward is for the mainland to fully prepare itself for war .. The historical turning point is getting closer."
For decades, Washington has stopped short of an explicit security guarantee for Taiwan. But as America stages a divisive presidential election, the Chinese government may doubt continuing US commitment to Taiwan. A window of opportunity could open after November 3 if the election result is disputed and Americans are plunged into crisis.
President Xi Jinping says reunification with Taiwan is a crucial part of the great rejuvenation of the Chinese nation. If America fails to defend Taiwan, US allies in the region will lose faith. Chinese hegemony in the Asia-Pacific is then inevitable and irresistible.
A full-scale Chinese assault on Taiwan would be formidably risky. Beijing will more likely attempt to erode Taiwanese morale and autonomy in small steps. The danger: Beijing might misread Washington's response.

Nork Wisdom

UK: Squandered Trust

Rachel Sylvester

Boris Johnson learnt from his father Stanley the motto: "Nothing matters very much, and most things don't matter at all."
The prime minister has sacrificed trust as he faces multiple crises. Negotiations with the EU depend on building a relationship of trust so that compromises can be broached in a spirit of honest exchange. But the prime minister has been playing politics all along. Nobody believes his claim that we are heading with "high hearts" for no deal.
If he is serious, the UK will be unprepared for the cliff edge. If he's not, then his games will make it harder to reach a free trade agreement by the end of the year.
Johnson has sacrificed the trust of the public and of his own MPs through his chaotic management of the coronavirus crisis. Trust has broken down between local and national politicians, between ministers and their scientific advisers, and even within the cabinet.

Britain as a Service

Robert Shrimsley

Brexit is now a fact. As a NATO and UN Security Council member, G7 economy and nuclear power, the UK still matters. A policy review draws on Brexiteer belief in UK exceptionalism to propose a model: Microsoft.
For Brexit Britain, the Microsoft model means marketing British values as a comprehensive service with limitless chances to upgrade. Buy into the UK and you get a champion of world order plus legal and education services and fintech expertise.
The UK is pushing the case for turning the G7 into a D10 group of democratic nations (adding India, South Korea, and Australia). An "Indo-Pacific tilt" will see a formal push to join the CPTPP with Japan, Australia, Canada, Mexico, Chile, and Vietnam.
Foreign secretary Dominic Raab is courting Vietnam. Indonesia, Malaysia, Singapore, and Thailand are also in focus. To adapt a Microsoft slogan, the UK wants to be "where's next" in a rising market.
The UK is wary of souring relations with China. And the tilt must not neglect Europe or its markets. History shows few European crises stop at the Channel.

UK Sick Man of Europe

Richard Horton

Global Burden of Disease 2019 tells an alarming story. On some of the most important measures of health, the UK is the "sick man" of Europe.
In 2019, life expectancy at birth in the UK was 82.9 years for a woman and 79.2 years for a man, with an average for both of 81.1. Spain and Italy both had an average of 83.1, France 82.9, Sweden 82.8, and Germany 81.2. The western European average was a year longer than in the UK.
Across the UK, Scotland has the lowest life expectancy (79.1), followed by Northern Ireland (80.3), Wales (80.5), and England (81.4).
The average healthy life expectancy for the UK in 2019 was 68.9 years. People in the UK spend an average 12.2 years living with some kind of illness. This is the worst healthy life expectancy of any other European country. There is an 8-year difference in life expectancy between northern and southern England. The lowest life expectancies track the upsurge in coronavirus.
Social inequality and a decade of cuts to social protections left many people in the UK vulnerable. A national revival is possible only if the government takes the health of its citizens seriously.

Good Riddance to Normal Life

Pilita Clark

I went back to the office for the first time in seven months the other day. A colleague who did the same thing said he had found his desk still covered in newspapers from the days before the building emptied in mid-March, plus a withered sandwich from the same era.
My desk looked exactly as I had left it. The rest of the office looked much same, except for the lavish supplies of hand sanitiser and face masks. Yet it was also deeply different, subdued, with only a few people, many working quietly alone.
A passing bus in a city street looks as it always did, until you see it has just one lonely, masked passenger. A store looks the same as ever until you see it has shut down. An office that still looks like an office is a pale version of what it once was.
The longer the pandemic goes on, the clearer it is that much of what was deemed to be normal life should have been binned years earlier.

$421 Million Peanut

President Trump paints a rosy picture of his financial condition, calling his debt coming due "a peanut" and saying he borrowed it as a favor to lenders.

End US National Crisis

The New York Times

Donald Trump's re-election campaign poses the greatest threat to American democracy since WW2.
Trump's ruinous tenure has gravely damaged the United States. He has abused the power of his office and denied the legitimacy of his political opponents. He has subsumed the public interest to the profitability of his business and political interests. He has shown a breathtaking disregard for the lives and liberties of Americans. He is unworthy of the office he holds.
During Trump's term, we have called out his racism and his xenophobia. We have critiqued his vandalism of the postwar consensus, a system of alliances and relationships around the globe that cost a great many lives to establish and maintain. We have deplored his divisive rhetoric and his malicious attacks on fellow Americans.

Johnson Hopes Trump Wins

Jonathan Freedland

The impact on the United States of a second Trump term would be transformative. But it would have a special impact on UK politics.
Boris Johnson says Brexiteers view a no-deal crash-out "with high hearts and complete confidence" and would feel boosted by a Trump victory. The Illiberal International embodied by Viktor Orban, Jair Bolsonaro, and Vladimir Putin would draw strength from it too. Although Johnson does not like to put himself in that company, he and his Brexit government would be lifted by US confirmation that the spirit of the age is not international cooperation but a world of competing states, each dedicated to making itself great again.
Defeat for Trump would signal that the populist fever had broken. With Trump gone, Johnson would look beached and alone.

American Global Dominance

Stephen Wertheim

The United States has no obvious purpose for vast global power. Both liberals and conservatives will face pressure to cut the trillions lavished on national security.
Eighty years ago, as it prepared to enter WW2, the United States made a fateful choice not only to pursue military supremacy but also to sustain it long into the future.
The American ruling class wished to interact and transact across the globe. Axis power endangered its expansive vision of itself. So long as totalitarians stalked the earth, the United States retained a coherent rationale for its costly pursuit of armed dominance.
When the Soviet Union collapsed, the United States was the global colossus. Today the United States deploys troops in more than 170 countries. Its military operates against terrorism in roughly 40% of the world's nations. Dozens of countries are targets of US sanctions.
Many in Washington now acknowledge excesses. Yet leaders in both parties say China is the adversary whose containment could restore purpose to American power.

The American Constitution

Edward Luce

Americans revere their constitution. Its separation of powers between the legislature (Congress), the executive (the presidency), and the judiciary (the Supreme Court) was designed to check the power of any one branch of government.
Donald Trump has stacked the Supreme Court with conservatives. Congress cannot stop him. A congressional staffer: "Trump treats subpoenas like toilet paper. There is almost nothing we can do about it."
Top of any liberal wish list of future amendments would be to scrap the electoral college. Twice in the past 20 years a US president has won election having lost the popular vote.
But the American constitution is a roadblock to change. A country that prided itself on its political radicalism now turns to the ancestor worship known as originalism.
University of Chicago Law School professor Eric Posner: "Originalism is a bit like the Protestant Reformation. You have to go back to the original text and read it literally."
A crisis is looming. Even if Joe Biden defeats Trump by a landslide, the Senate could block him just as it blocked Barack Obama. Also, the Supreme Court would strike down an obligation on everyone to buy health insurance under Obamacare.
Berkeley law professor John Yoo: "America was designed to be a republic, not a democracy. By design, change is hard to bring about. The founders deliberately built in protections against the tyranny of the majority."
Republican senator Mike Lee: "We're not a democracy. The word 'democracy' appears nowhere in the constitution."

WEIRD

Daniel C. Dennett

Early Christian fathers said: Don't marry your cousin! Joseph Henrich says this prohibition changed the face of the world, by eventually creating societies and people that were WEIRD: Western, educated, industrialized, rich, democratic.
Roughly, we weirdos are individualistic, think analytically, believe in free will, take personal responsibility, feel guilt when we misbehave, and detest nepotism. The rest identify more strongly with family, tribe, clan, and ethnic group, think more holistically, take responsibility for what their group does, feel shame when they misbehave, and see nepotism as a duty.
WEIRD folk are a recent development, growing out of the innovation of agriculture about 10,000 years ago, the birth of states and organized religions about 3,000 years ago, and early weird steps over the last 1,500 years, culminating in the modern world in the last 500 years or so.

Chemical Origins of Metabolism

John Rennie

A central pillar of all cellular metabolism is a complex 10-step chemical process variously known as the tricarboxylic acid (TCA) cycle, the citric acid cycle, or the Krebs cycle. We suspect the TCA cycle was one of the early reactions to establish itself in the prebiotic soup.
We now know glyoxylate and pyruvate react to make a range of compounds that include chemical analogs to all the intermediary products in the TCA cycle except citric acid. These products all form in water within a single reaction vessel, at temperatures and pH conditions mild enough to be compatible with conditions on Earth.
This is not yet a cycle. But precursors of cells with those molecules at their disposal might have performed some of the synthetic chemistry useful to life. A linchpin of modern metabolism could have emerged under minimally demanding conditions.

Brexit Seen From Germany

Paul Mason

Boris Johnson is preparing for years of rhetorical conflict with the EU. Ministers no longer care whether they get a deal or default to WTO rules, because the economic costs are swamped by the Covid-19 recession and its fiscal black hole.
Faced with Johnson's posturing, European governments and institutions have shifted their priorities. The EU will pool its economic response to the Covid-19 pandemic. The German government has thrown aside fiscal conservatism and extended its wage subsidy scheme until the end of 2021.
Germans now see the Brexit project as an attempt to create a state-subsidised chumocracy with no clear global purpose. German foreign policy is consolidating the European economy by adopting a tough approach to Russia and switching its focus from China to Japan.
Johnson has a weak position. Because the UK opted to leave the EU, and Johnson aims to adopt different laws and standards, an economic border has to be drawn between the two entities. To get a deal, Johnson opted to draw that border in the Irish Sea.
If Johnson reneges on his deal, the UK may lose access to the biggest market in the world, be forced by an international court to accept a customs border on its own territory, and still pay the EU billions for the privilege.
Johnson seeks confrontation with Europe to please old English Tories. He will use the Withdrawal Agreement as German fascists once used the Treaty of Versailles.

Last Saturday, Donald Trump, 74 and clinically obese, woke up in the presidential suite at the Walter Reed medical center in Bethesda, Maryland. Seven doctors in face masks emerged from the hospital to say he was beating the coronavirus.
Apart from supplemental oxygen, the treatment consisted of an experimental antibody cocktail, the antiviral drug remdesivir, and the steroid dexamethasone. The steroid can cause manic behavior.
On Sunday evening, Trump rode in an armored limousine outside the hospital and waved to supporters. Experts said he was endangering his Secret Service detail in the airtight vehicle. An attending physician at Walter Reed called the stunt insane.
On Monday, just in time for the evening news, Trump took a triumphant helicopter flight back to the White House, climbed a staircase to the balcony, gave a double thumbs up, peeled his mask off, and staged a "Mussolini moment" of macho rhetoric punctuated by labored breathing. Then he unleashed a blitzkrieg of wild tweets.
On Tuesday, Trump again compared Covid-19 to the seasonal flu, just as he did at the start of the pandemic. He tweeted videos of his sunset return accompanied by heroic music: "Nobody that is a leader would not do what I did. And I know there's a risk, there's a danger, but that's OK. And now I'm better. Maybe I'm immune! I don't know."
On Wednesday, Trump returned to work in the Oval Office and let rip with another fusillade of tweets. He claimed his infection was "a blessing from God" and gave an interview on the Fox Business channel: "I'm feeling good, really good. I think perfect."
Former Obama chief strategist David Axelrod: "This POTUS has turned his own political suicide into a surreal reality show."

Trumpism unmasked
Jonathan Freedland

Donald Trump tried to blame his infection on the grieving relatives of slain soldiers: "They want to hug me and they want to kiss me."
Trump said his attorney general William Barr would find himself in a "sad, sad situation" if he didn't indict Barack Obama, Hillary Clinton, and Joe Biden for "the greatest political crime in the history of our country" — the inquiry into his campaign links to Russia.
On Thursday, when 13 men were arrested in Michigan over a violent plot to kidnap the state governor and try her for treason, Trump fired off a rebuke to the governor for failing to say thank you to "my justice department" for uncovering the conspiracy.
Trump thinks he can do whatever he likes, and to hell with the "suckers and losers" who suffer as a result. His disdain for facts and for science has cost the lives of more than 200,000 Americans.

Brexit: No Surrender

The Times

EU chief negotiator Michel Barnier says a UK−EU post-Brexit agreement is close but urges European leaders to demand further UK concessions and not let the EU summit next week become a negotiating deadline.
European Council president Charles Michel says there will be no agreement unless the UK prime minister makes "significant" concessions: "This is the moment of truth."
UK Cabinet Office permanent secretary Alex Chisholm is concerned that UK business is not taking the deadline seriously: "There isn't going to be an extension and they really need to be ready."

AR I encourage the EU to stay hard. The UK under the present government is heading for a historic fall. If a no-deal Brexit occurs as Boris Johnson threatens, the mess that follows will condemn him and all his minions and works to one of the deeper pits of hell for the rest of recorded history.

Nobel Chemistry: CRISPR

Quanta

Emmanuelle Charpentier of the Max Planck Institute for Infection Biology, Berlin, and Jennifer Doudna of the University of California, Berkeley, have been awarded the 2020 Nobel Prize in Chemistry for their development of CRISPR/Cas9 genetic editing.
In a 2012 paper, they showed that key components of the ancient immune system found in bacteria and archaea could be retooled to edit DNA.
Genome editing is now commonplace in laboratories around the world. It has enabled researchers to probe the functions of genes at will, to innovate new methods of plant breeding, and to develop promising new gene therapies.
Most prokaryotic organisms have an odd structure in their genome. A portion of their DNA consists of many short, repetitive base sequences, interspersed with other short, variable spacer sequences, a.k.a. CRISPR, for clustered regularly interspaced short palindromic repeats. Next to the portion is a CRISPR-associated system (Cas) of genes for enzymes that can cut DNA.
The CRISPR/Cas system might serve as a kind of immune system for fighting persistent viral attackers. When bacteria survive a viral infection, they store tiny fragments of scavenged viral DNA in the CRISPR part of their own genome for future reference. If the same virus attacks again, the bacteria can somehow use the viral DNA on file to direct Cas enzymes at the invaders.
Charpentier and Doudna borrowed this genome slicing capability from the bacteria and turned it into a more general genome editing tool, with the CRISPR genetic structure as a targeting tool and the Cas9 enzyme to do the cutting.

AR A cut-and-paste tool for genes — brilliant.

Bodge Back Better

Financial Times

In his keynote speech to a virtual Conservative conference, UK prime minister Boris Johnson tried to quell party criticism of his leadership and concerns over his big state interventions in the UK economy and erosion of civil liberties during the coronavirus crisis.
Johnson: "I've read a lot of nonsense recently about how my own bout of Covid has somehow robbed me of my mojo. This is self-evident drivel, the kind of seditious propaganda you would expect from people who don't want this government to succeed."
He said wars and plagues can trigger "acceleration of social and economic change" and the UK cannot return to life as it was before the pandemic. He aims to fix the social care system and the "broken" housing market and plans a green energy revolution, a hospital building program, and a national advanced research and projects agency.
In his vision of the UK in 2030, Britons would return from a trip abroad on a zero-carbon passenger jet made in the UK, flash their "Brexit blue passport" and see a country at the cutting edge of technology, with excellent education and health services.

High Time for a Nobel

The Times

Roger Penrose received a phone call while "stark naked in the shower" to tell him he had won the Nobel prize for work he published in 1965. Sir Roger, 89, said it was perfectly timed: "If you've got grand ambitions, it's bad to get a Nobel too early. [It] gets in the way of your science."
Einstein's theory of general relativity predicted that big spherical masses could collapse to objects so dense that no light could escape. Penrose found a way to prove that even nonspherical stars imploding asymmetrically could become black holes. He followed through on the idea in collaboration with Stephen Hawking.
Astronomer royal Martin Rees: "He and Hawking together showed that the development of a singularity, where the density goes infinite, was inevitable once a threshold of compactness had been crossed .. Sadly, this award was too much delayed to allow Hawking to share the credit."

AR The text in The Times concludes with an irrelevant anecdote about toilet paper.

 

Milky Way Prizes

Nature

2020 physics Nobelist Sir Roger Penrose OM FRS, Rouse Ball professor emeritus of mathematics at the University of Oxford, demonstrated how, according to the general theory of relativity, black holes could form under realistic conditions and would give rise to singularities.
Rival teams led by 2020 physics Nobelists Andrea Ghez and Reinhard Genzel used the Keck Observatory in Mauna Kea, Hawaii, and the Very Large Telescope in Paranal, Chile, to study the stars at the centre of the Milky Way. They mapped a dense cloud of stars at the centre buzzing around at high speeds, consistent with the radio source Sagittarius A* marking the site of a supermassive black hole with a mass of several million ⦿.
Crucial to the mapping was finding ways to boost image resolution. The teams first used speckle imaging to cancel the distortion caused by the turbulence in Earth's atmosphere and later used adaptive optics to correct for the distortion. This let them track the motion of stars in 3D.
The conclusion that there is a supermassive black hole at the centre of the Milky Way was the culmination of big team efforts.

A big hole
Science

Roger Penrose proved that in general relativity the gravitational collapse of a big enough mass into a black hole is inevitable. Whatever you do to the hole, its event horizon will only grow.
Nobel physics committee member Ulf Danielsson: "Penrose laid a theoretical foundation so that we could say, yes, these objects exist. We can expect to find them if we go out and look for them."
The Sgr A* black hole has a mass of 4 M⦿ and is 250 Em away. The teams led by Andrea Ghez and Reinhard Genzel made a movie of a star near it and proved it was orbiting a huge mass.

AR You can see a fine example of a nonperiodic pattern known as a [Roger] Penrose tiling on the courtyard of the Andrew Wiles Building, Mathematics Institute, University of Oxford.

 

Black Holes Are Real

Quanta

Black holes are regions that contain so much matter packed within so little space that gravity collapses the matter toward a central singularity. Everything within a certain distance of the singularity becomes gravitationally trapped, even light.
Roger Penrose showed in 1965 that black holes actually form in the universe. He showed that deviations from spherical symmetry cannot prevent spacetime singularities from arising. A trapped surface is a closed 2D surface that lets light in but not out, and he found that space and time switch roles inside a trapped surface. Time points toward the center, so escaping a black hole is as impossible as going back in time.
Reinhard Genzel and Andrea Ghez led teams that studied the center of the Milky Way. They pioneered approaches to remove the blur of Earth's atmosphere. Speckle imaging involved combining multiple brief exposures, each short enough to avoid extended atmospheric distortion. Adaptive optics involves beaming a laser into the night sky, creating an artificial star that reveals atmospheric distortions, which are then counteracted by small actuators deforming the telescope mirror in real time.
Both teams observed a star, S2, that orbits close to the compact object in the galactic center known as Sagittarius A*. The trajectory of S2 proves that Sagittarius A* is smaller than 125 AU, even though its mass is 4 M⦿. It can only be a supermassive black hole.

AR I this stuff.

Penrose Wins Nobel

Royal Swedish Academy of Sciences

The Nobel Prize in Physics 2020 goes to:
 Roger Penrose, University of Oxford, UK
 Reinhard Genzel, Max Planck Institute for Extraterrestrial Physics, Garching, Germany,
    and University of California, Berkeley, USA
 Andrea Ghez, University of California, Los Angeles, USA
Penrose wins half of the 10 million Swedish kronor (almost €1 million) prize for his discovery that black hole formation is a robust prediction of the general theory of relativity. He proved in 1965 that black holes really can form and described them in detail. His proof used ingenious methods to show that black holes are a direct consequence of Albert Einstein's general theory of relativity.
Genzel and Ghez share the other half for their discovery of a supermassive compact object at the center of our galaxy. They each lead a group of astronomers that focused on the Sagittarius A* region and mapped the orbits of the brightest stars closest to the middle of the Milky Way. They found an invisible object of around 4 million solar masses within a region no larger than our solar system. They developed methods to see through interstellar gas and dust to the center of our galaxy and refined new techniques to compensate for distortions caused by the Earth's atmosphere. Their work has given us the most convincing evidence yet of a supermassive black hole at the center of the Milky Way.
Nobel committee for physics chair David Haviland: "The discoveries .. have broken new ground in the study of compact and supermassive objects. But these exotic objects still pose many questions that beg for answers and motivate future research."

AR The Nobel prize committee has at last accepted that black holes are real. The big prize for Penrose may reflect the fact that they missed the chance to award a Nobel to Stephen Hawking, which many of us thought he deserved.

The Future of Tropical Forests

Arie Staal et al.

Tropical forests modify the conditions they depend on through feedbacks that shape their resilience to deforestation or climate change.
By looking at local-scale tipping points and regional-scale forest-rainfall feedbacks across the tropics under the recent climate and a severe climate-change scenario, we find that forest-rainfall feedback expands the geographic range of possible forest distributions, especially in the Amazon. The Amazon forest could partially recover from complete deforestation but may lose that resilience later this century. The Congo forest currently lacks resilience, but is predicted to gain it under climate change, whereas forests in Australasia are resilient under both current and future climates.
Our results show how tropical forests shape their own distributions and create the climatic conditions that enable them.

AR Rainforest resilience — hmm.

Schadenfreude

Lea Boecker

Bei Donald Trump kommen sehr viele Auslöser für Schadenfreude zusammen:
 Die Überlegenheit und Dominanz eines Menschen: Vor allem Menschen, die ihren Status durch Dominanz und Einschüchterung anderer erlangt haben, auslösen Schadenfreude.
 Ob die Person das Unglück verdient hat, weil sie sich womöglich ignorant und überheblich gegenüber Risiken gezeigt hat: Wenn dieser Person ein negatives Ereignis widerfährt, fühlt sich das gerecht und manchmal sogar befriedigend an.
 Abneigung gegenüber Personen oder deren Gesinnung: Auch da bietet Trump breite Angriffsfläche.
Trump hat sich überlegen präsentiert und hat die Gefahr des Virus kleingeredet. Rutscht eine solche Person ab, wird Schadenfreude hervorgerufen.
Schadenfreude anzeigt, dass Gerechtigkeit hergestellt wird. Wenn jemand sich moralisch fragwürdig verhalten hat und in der gleichen Domäne abgestraft wird, fühlt sich das für viele Menschen, als würde die Welt nach gerechten Regeln funktionieren.

Proud Boys

Sarah Baxter

I was in Cleveland, Ohio, ahead of the presidential election TV debate there. Proud Boys wearing army camo and carrying guns milled around their white battle bus.
In the debate, Donald Trump said: "Proud Boys, stand back and stand by. But I'll tell you what .. somebody's got to do something about Antifa [anti-fascists] and the left."
The Proud Boys were ecstatic. Trump's call-out and "What are your orders, Sir!" were soon on PB shirts selling on Amazon.
Cleveland Proud Boy Mike, 33: "We handle security for events. If Antifa show up, it's good to have us and make sure nobody's going to be a problem. We're not going to beat someone to a pulp, we're more like bouncers."
Aaron showed me his Ruger AR 566 semi-automatic rifle, with ammo clip modified to hold more bullets. Inside their battle bus, guns were mounted under the windows.
Native Brit Gavin McInnes launched Proud Boys in 2016. They say rights for women and gays show West is best. They wear black Fred Perry shirts trimmed with yellow for an "an-cap" message: black for anarchy, yellow (gold) for capitalism.
Their British allies include English Defence League brawler Tommy Robinson. Mike: "If he was in America, he'd be a Proud Boy."
The group's name is taken from the song Proud of Your Boy in the Disney stage musical Aladdin: "Believe me, bad as I've been Ma, you're in for a pleasant surprise."
The Proud Boy battle bus pumped out music: "If Heaven ain't a lot like Dixie, I don't wanna go," by Hank Williams Jr.
Proud Boy degrees of membership include swearing allegiance to the fraternity, getting beaten up until they can recite the name of five cereal brands, adhering to a "no wanks" pledge, and getting a Proud Boy tattoo.
Aaron, 33 and single, says the ban on wanking "does wonders for your determination, energy levels, and productivity" but doesn't make them misogynists: "We want to put women back on their pedestal."

Number 10 later admitted the already existing Civil Contingencies Act required parliament to renew the government's authority every 30 days. The Coronavirus Act imposes only a six-month renewal date on the government.
Number 10 owns the past six months. The role of Dominic Cummings is an ongoing insult. When the coronavirus crisis hit, Conservative MPs watched Cummings display the same contempt toward the public that he has shown toward them.

How Science Works

Joshua Rothman

Michael Strevens says pursuit of scientific studies requires an inhuman degree of focus on facts. The single greatest obstacle to successful science is the difficulty of persuading brilliant minds to give up the intellectual pleasures of speculation and theorizing and to turn instead to a life of producing experimental data.
An iron rule tells scientists not what they can think but what arguments they can make as scientists: They must uncover or generate new evidence to argue with, and they must conduct all disputes with reference to empirical evidence alone.
In the prescientific world, thinkers tended to inquire into everything at once. Often, they arrived at conclusions about nature that were fascinating, visionary, and wrong. Looking back, we usually say they were insufficiently methodical and empirical.
The iron rule bids thinkers to rely only on evidence they can verify. It lets scientists step away from the quest for completeness. By authorizing shallow explanation, the iron rule offers an empirical bridge across a conceptual chasm.
Without the iron rule, quantum physicists would be arguing endlessly about metaphysics. Following the iron rule, they can make progress empirically even though they are uncertain conceptually. We can spend billions of dollars on huge machines to explore the quantum world.
Strevens says the iron rule created science. Scientists are people who like to win, but this is part of the scientific game. Winners have to follow the iron rule.

AR So far so good, but theory counts too.

 

Primordial Cosmic Strings

Thomas Lewton

In the beginning, all the forces of nature may have been unified. But as the universe expanded and cooled, this superforce condensed into the familiar forces.
The cosmos may have cooled so quickly as to crumple the fabric of spacetime, creating a network of energetic cracks in spacetime stretching across the observable universe.
We may have glimpsed evidence of these cosmic strings. NANOGrav astronomers looked at 12 years of data from dozens of pulsars and found the timing of the pulsar blips was distorted as if by gravitational waves.
Pulsars are precise cosmic timekeepers. Gravitational waves that change the arrival time of their blips on Earth could come from the thrumming of cosmic strings, collisions of supermassive black holes, or other violent cosmic processes.
Any cosmic strings grew with the universe. Every so often, they crinkled up or hit other strings, causing loops to pinch off in bursts of energy. These loops vibrated for billions of years, losing energy as gravitational waves.
Alternatively, the NANOGrav signal came from supermassive black hole mergers or from primordial black holes.

AR As usual, we need more data.

US Tax System Broken

The New York Times

Before he became president, Donald Trump lived lavishly while paying little in federal income taxes. He lived a life of comic excess and yet, in many years, paid nothing in federal income taxes.
The 400 wealthiest households paid 70% of their total income in taxes in 1950, 47% in 1980, and 23% in 2018. The share of all tax returns subject to an audit declined by 46% from 2010 to 2018, but by 61% for millionaires.
The rich keep getting richer, while the Internal Revenue Service keeps getting smaller. Cracking down on rich tax cheats is a basic function of government to ensure that people are playing by the rules.
Adding $40 billion to the IRS budget over the next decade can yield at least $103 billion in tax revenue, says the CBO. Natasha Sarin and Lawrence Summers say restoring IRS funding and modernizing collection will let the government collect $1 trillion of unpaid taxes.

Donald J. Trump paid $750 in federal income taxes the year he won the presidency. In his first year in the White House, he paid another $750. He had paid no income taxes at all in 10 of the previous 15 years.
Trump faces hundreds of millions of dollars in debt coming due that he has personally guaranteed. Also hanging over him is a long audit battle with the Internal Revenue Service over the legitimacy of a $72.9 million tax refund he received after declaring huge losses.

Germany: 30, 71, 149, 1220?

Timothy Garton Ash

Germany is 30 years old on October 3. Or 71, counting from the foundation of the Federal Republic in 1949. Or 149, if we go back to the unification of the German Reich in 1871. Or 1220 years old, if we start the First Reich with the coronation of Charlemagne in 800 CE.
In any case, the last three decades have been the best. In a world roiled by populism, fanaticism, and authoritarianism, the Federal Republic is a global beacon of stability, civility, and moderation.
German democracy has not yet faced a really major economic crisis. This is due to its great economic strength, to export markets such as China opened up by globalization, to trading with the euro, and to a reservoir of cheap skilled labor in Europe.
Germans were amazed and appalled by Brexit. Then they were contemptuous of the mess Britain is making of it. If they had done anything like it, they would have convened a cross-party Bundestag commission to work out a sober, rational plan for implementing it.
Being embedded in the European Union has an existential significance for Germany that it does not have for Britain. It is possible to imagine an EU without Britain. It is impossible to imagine an EU without Germany.
The First Reich — the Holy Roman Empire — is a fact of German history. German medieval and early modern history involved multiple layers of law, sovereignty, and authority. The German future is inseparable from that of the European Union.

AR I concur with this view.

US Supreme Court

President Trump's promise to name a woman to replace Ruth Bader Ginsburg was cynical and insulting to the millions of women who view the late Supreme Court justice as a feminist icon. His pick, Amy Coney Barrett, is no Ruth Bader Ginsburg.
The next Supreme Court justice will vote on women's rights to control their own bodies and to gain access to affordable health care. Whether she is a woman matters less if she does not support the causes Justice Ginsburg championed.

UK in Crisis

The Observer

A curfew was imposed by the governments in Westminster, Wales, and Scotland last week.
The UK testing system has been overwhelmed. There was no strategy to prioritise access to testing, while 90% of tests take more than 24 hours to return a result.
Thousands of students are now trapped in student halls after moving to start their courses when their teaching is online and social activities are restricted.
As the furlough scheme comes to an end, millions are likely to suffer months or years of unemployment on paltry levels of benefit, with little support for retraining.
Backbench libertarians concerned about the economic impact of further restrictions say there is no point in doing more than shielding the most vulnerable.
Considering both economic cost and mental health, it would be better to take tough action now rather than leave it too late and risk a full lockdown.
Instead of building social solidarity, the prime minister is trying to shift the blame.

Sweden

Sweden has no need to curtail civil liberties and wreck the economy to curb Covid-19. Its government merely imposed a ban on gatherings of more than 50, restrictions on visiting care homes, and a shift to table-only service in bars.
Sweden offers an escape from the social catastrophe now engulfing the UK. Brits need Swedish levels of sickness benefit to ensure that carriers stay at home and quarantine, of housing benefit to avoid eviction from those same homes, and of unemployment benefit and retraining.
Covid-19 is exposing the lack of social solidarity in Britain. By not locking down in the spring, Sweden had a more protracted Covid-19 outbreak, with far more deaths per capita than its neighbours. But the UK death rate was worse because no other European country put the village idiot in charge.

America vs Europe

Luke McGee

US president Donald Trump is no fan of the EU. He talks positively about Brexit and claims the EU wants to "take advantage" of the United States.
US ambassador to the Netherlands Pete Hoekstra hosted an event at his embassy for Forum for Democracy (FvD), a far-right, anti-immigration, and anti-EU party.
Former Dutch MEP Marietje Schaake: "The Trump administration has shown time and again that its allies are the Euroskeptics like [Nigel] Farage and FvD, not the governments of the day."
Trump has appointed a number of divisive ambassadors like Hoekstra in Europe who erode transatlantic ties, enrage their hosts, and represent Trump's personal interests in Europe.
Trump's ambassador to UK Woody Johnson was alleged to have used his position to lobby for the British Open golf tournament to be held on one of Trump's golf courses. He also openly supported Brexit.
Within hours of starting the job, former US ambassador to Germany Richard Grenell tweeted: "German companies doing business in Iran should wind down operations immediately."
Trump praised Euroskeptic Hungarian prime minister Viktor Orban during his trip to the White House last year: "Highly respected, respected all over Europe. Probably, like me, a little bit controversial, but that's OK."
A German diplomat: "Trump and his diplomats have given the impression that they want to punish the EU for some reason or another."
A senior EU official: "Under Trump, it seems [US officials] never miss a chance to try and undermine the EU .. we started to see it as an opportunity to be more independent in certain areas like defense and geopolitics."
Schaake: "The transatlantic relationship is robust. But the ability for the two sides to work together, both bilaterally and as a united front on the global stage, has been undermined by the Trump administration."

UNGA Remarks

Donald Trump

I have the immense privilege of addressing you today as the elected leader of a nation that prizes liberty, independence, and self-government above all.
The United States, after having spent over $2.5 trillion since my election to completely rebuild our great military, is also, by far, the world's most powerful nation.
The free world must embrace its national foundations. It must not attempt to erase them or replace them. If you want freedom, take pride in your country. If you want democracy, hold on to your sovereignty. And if you want peace, love your nation. Wise leaders always put the good of their own people and their own country first.
The future does not belong to globalists. The future belongs to patriots. The future belongs to sovereign and independent nations who protect their citizens, respect their neighbors, and honor the differences that make each country special and unique.
China declined to adopt promised reforms. It has embraced an economic model dependent on massive market barriers, heavy state subsidies, currency manipulation, product dumping, forced technology transfers, and the theft of intellectual property and also trade secrets on a grand scale. To confront these unfair practices, I placed massive tariffs on Chinese-made goods.
America will never be a socialist country. We must always be skeptical of those who want conformity and control. We in America believe that every child, born and unborn, is a sacred gift from God. The United States will always uphold our constitutional right to keep and bear arms.
Liberty is only preserved, sovereignty is only secured, democracy is only sustained, greatness is only realized, by the will and devotion of patriots.

America Endures Trump

David Smith

Donald Trump held a White House press conference and careered from touting miracle vaccines to building supreme court suspense to kneecapping American democracy.
The first question went to Playboy reporter Brian Karem: "Will you commit to make sure there's a peaceful transferral of power after the election?"
Trump: "We're going to have to see what happens, you know that. I've been complaining very strongly about the ballots, and the ballots are a disaster."
Karem: "I understand that, but people are rioting. Do you commit to make sure that there's a peaceful transferral of power?"
Trump: "Get rid of the ballots and you'll have a very peaceful — there won't be a transfer, frankly. There will be a continuation. The ballots are out of control. You know it."
Karem later tweeted: "This is the most frightening answer I have ever received to any question I have ever asked. I've interviewed convicted killers with more empathy."

Germany After Merkel

Roger Boyes

Angela Merkel has barely a year left in office before the autumn 2021 election. Polls show the CDU on 36%, SDP on 14%, Greens on 22%, and AfD on 8%. Two CDU men are jockeying to replace her.
Foreign affairs committee chair Dr Norbert Röttgen would be tougher on Russia and China and more active in NATO. Friedrich Merz spent years in business, and some fear he would undo years of social liberalism.
Röttgen says the CDU should stop being afraid of the far right now the migrant crisis has relaxed. If Germany can take more refugees, the gesture would help him to forge a coalition with the Greens.
The time is coming for a CDU-Green pivot as climate change targets start to press and Covid-19 starts to fade. Earlier, Röttgen was environment minister and argued for an end to nuclear power.
Röttgen wants to scrap the Nord Stream 2 gas pipeline agreement with Russia and wants to get rid of Huawei involvement in German 5G. These are the battle lines.

AR I find Dr Röttgen sympathetic.

 

Primordial Black Holes

Joshua Sokol

LIGO data shows there must be more black holes out there than we thought.
Primordial black holes may have been born during the Big Bang. The first LIGO data in 2016 revived the primordial black hole hypothesis. But then a 2017 calculation showed that if the baby universe spawned enough black holes to account for dark matter, then over time, they black would merge at rates thousands of times higher than LIGO sees.
In a paper published last week, Karsten Jedamzik shows how a large population of primordial black holes could perfectly match what LIGO observes.
We think small primordial density fluctuations left some regions with enough mass to collapse into a black hole. A few μs ABB, the universe cooled enough for quarks and gluons to bind into protons and neutrons. The pressure drop may have helped more regions collapse into black holes.
As the universe kept cooling, other particles formed, with another pressure drop and maybe more black holes. The first black holes sucked in about one solar mass of material from within their event horizon. The second round may have taken about 30 ⦿, like the holes first seen by LIGO.
Primordial black holes would form binaries. Jedamzik calculated that in a universe teeming with black holes, a third black hole would often approach the initial pair and change places with one of them. This process would repeat again and again.
Over time, this swinging from partner to partner would leave binary black holes with almost circular orbits. These pairs would be very stable. Even a huge population of primordial black holes would fit LIGO observations.
Primordial black holes would sit in dark clusters a few light years in diameter — just where we imagined dark matter.

AR At last we can forget wimps and machos.

Trump America

Frank Bruni

President Donald Trump gets three Supreme Court appointments. Seldom has a president's impact been so inversely proportional to his warrant.
President Barack Obama appointed 2 Supreme Court justices, George W. Bush 2, Bill Clinton 2, George H.W. Bush 2, Ronald Reagan 3.
If Trump acts before the election, he'll match Reagan's tally in half the time, with a mere fraction of his popular support and respect.
America has become a country where the minority rules. In 2018, Democrats won 22 of the 35 Senate elections, with candidates who got roughly 17 million more votes than the Republican candidates got. Yet the Senate is controlled by Republicans.
Trump is president because of the Electoral College. Joe Biden might have to win the popular vote by more than 5 million ballots to be sure of an Electoral College victory.
A Supreme Court with three Trump appointees could act on abortion, gay rights, voting rights, and affirmative action.

Putin Russia

The New York Times

Alexei Navalny was poisoned with Novichok. Did President Vladimir Putin order or approve the attempted assassination?
Even if it was an operation ordered at low level, the attack on Navalny breaks new ground. Attacking two former Russian double agents, Sergei Skripal by nerve gas and Alexander Litvinenko by radiation, is hard to exceed in brazenness.
Navalny was not a former spy but a popular and visible political opponent of Putin. His exposés of official corruption were widely circulated, detailed, and credible. Those who tried to kill him were attempting to silence him.
Russia is a signatory to the Chemical Weapons Convention, and after Germany established that Navalny had been poisoned, the Organization for the Prohibition of Chemical Weapons stated that any poisoning of an individual through the use of a nerve agent is considered a use of chemical weapons.
President Trump has largely closed his eyes to Putin's serial transgressions.

Rage: Trump Unleashed

Peter Conrad

Donald Trump on Bob Woodward "I love this guy, even though he writes shit about me. That's OK."
"I bring rage out," Trump tells Woodward. Like every statement he makes, it was a boast. Much as he dotes on adulation, he is equally happy to be loathed, and he regales Woodward with video clips: "See the hate!" he says, weirdly elated.
Having tracked his antics all year, Woodward ends with a solemn reminder of the president's constitutional duty. Trump was alerted to the imminence of a deadly pandemic in January yet went on saying Covid-19 was a hoax concocted by the Democrats.
Trump allowed Woodward to record their interviews, so this is an oral history in which a self-obsessed but blithely unself-aware blabbermouth blows the whistle on himself.
"I'm comfortable," he says when questioned about the virus. "I'm comfortable. I'm comfortable." Later the contagion is wished away in an almost musical crescendo: "It's gonna go. It's gonna leave. It's gonna be gone. It's gonna be eradicated."
Trump's monologue is autocratic. "The ideas are mine, Bob," he insists. "The ideas are mine. Want to know something? Everything's mine. You know, everything is mine."
When Woodward asks about underprivileged Americans, Trump says: "I'm not feeling the love."

AR He seems not to be feeling the hate either.

RAGE

David Smith

Donald Trump was piqued that he did not take part in Bob Woodward's previous book, Fear, so was determined to give his version of events for Rage. But there are moments when he seems too eager.
Woodward recalls a "surreal time" starting last December, when Trump initiated seven phone calls, conjuring the image of a president rambling around the White House at night without much else to do: "I call him the night prowler. I think it's true. He doesn't drink. He has this kind of savage energy."
Woodward: "He allowed me to press him personally and I could do an interrogation of him that the House and the Senate could not do on impeachment. I let him have his say .. I learned an awful lot about his attitudes .. It's all there."
The book opens with a secret briefing on 28 January. National security adviser Robert O'Brien warns Trump: "This will be the biggest national security threat you face in your presidency."
Trump told Woodward in February the coronavirus was "more deadly than even your strenuous flus" yet publicly minimized the risk: "I wanted to always play it down. I still like playing it down, because I don't want to create a panic."
Woodward: "It's a grotesque, sad, tragic failure .. The historians are going to put it all together as the lost month of February 2020."
Woodward reaches an unequivocal conclusion: "Trump is the wrong man for the job."
Woodward says Trump was elected to violate norms: "That's what the expectation was. We missed the pivot in history .. The old order before was dying and it was replaced by a new order."

Loser wins
Josh Glancy

The Donald Trump who emerges in Bob Woodward's book is a confidence man, always closing, always boasting, twisting, overstating.
Imagine a president hearing one thing from his health and security advisers, and then turning around and telling the American people the exact opposite.
His boosters say Trump wanted to avoid undue panic in a crisis. This defence ignores the vast middle ground between panicking and deceiving the people.
Millions of Americans failed to take the virus seriously enough, early enough. More masking, more distancing, more gravity in the public sphere would likely have saved lives.
Trump's former director of national intelligence Dan Coats: "It's just what he thinks. He doesn't know the difference between a truth and a lie."
Optimism in the face of all things is the secret. Total, unwavering self-belief no matter the facts is a powerful force. Trump wins even as he loses.

AR I'm reading Rage now — very enjoyable.

Boris Johnson is a man with "misery etched on his face" as Covid and money troubles wear him down. He has lost 10 kg since April and is said to be missing his former wife Marina Wheeler despite his new relationship with Carrie Symonds.
Sir Humphry Wakefield, father-in-law of Dominic Cummings and a former colonialist, told a visitor to the family's ancient and historic Chillingham Castle in Northumberland that Johnson was hit so severely by Covid in the spring that he would quit his job next year.
A witness at a Commons meeting with Johnson last week: "He certainly wasn't as lively as you'd expect. Does that go back to the illness? Is it the weight of responsibility or is it maybe just a recognition that he's not always very well briefed on things?"
Johnson has money worries. His income has dropped from more than £350,000 a year as a backbench MP, including £275,000 from the Daily Telegraph, to just £150,000 as prime minister. He has to pay taxes and buy food. He is still providing for four of his children and paying for his divorce.

A veteran Conservative MP: "It's driving me bonkers. We're in one hell of a mess."
Johnson may have to start listening to parliament. His promise to deliver a trade deal with the EU is a key test. Coronavirus is also a big test, where MPs attack him over the testing system and for failing to get a grip.

Math and Particle Physics

Charlie Wood

QED, quantum electrodynamics, is a pillar of the standard model of particle physics, but it was glued together with a hack called renormalization.
Richard Feynman and others made the hack. When a QED calculation leads to an infinite sum, cut it short. Put the part that wants to become infinite into a coefficient in front of the sum. Replace that coefficient with a finite measurement from the lab. Then let the new sum go back to infinity.
Feynman: "It's what I'd call a dippy process."
In QED, the electron has two charges: an infinite theoretical charge and a finite measured charge. Quantum field effects cloak the electron, so we measure a small net charge.
We now say effective charge varies with distance. The more you zoom in, the more charge you see. Renormalization is like a zoom lens.
The Ising model is a grid of atomic arrows pointing up or down that predicts the behavior of magnets. At low temperatures, most atoms align, magnetizing the material. At high temperatures, they grow disordered and the lattice demagnetizes. The way things vary around a critical point looks identical in the Ising model, in real magnets of varying materials, and even in unrelated systems.
A block spin technique breaks a complex Ising grid into modest blocks with a few arrows per side. The average orientation of the arrows in a block is the value for the block. Repeating the process blurs away fine details.
Ken Wilson united these ideas in his renormalization group. The group justified QED and made a ladder between the scales of universal systems, like a theory of theories connecting big and small. It changed physics forever.
The renormalization group helps identify which big quantities to measure and which details to ignore. Feynman was right to renormalize QED because the theory works best over a certain size range. Renormalization zooms out from small scales.
Zooming in closer is a major goal of new physics.

AR I find this stuff important.

MPs say the UK coronavirus test and trace system is "barely functional" and demand is many times capacity.
NHS test-and-trace program head Dido Harding: "I strongly refute that the system is failing."
Fewer than 2% of people using a home test kit in England got their results within 24 hours in the week to 9 September. One third of results from in-person tests were turned around within 24 hours, down from two thirds the previous week.
Harding: "We made a conscious decision because of the large increase in demand to extend the turnaround time in order to process the number of tests in the last couple of weeks."
A contact tracer: "Some people are being told by test and trace that they need to self-isolate when their isolation period has been and gone."
Liberal Democrats health spokesperson Munira Wilson: "The testing system is in meltdown. People can't access tests, turnaround times are down, cases are rising. The government is at risk of losing control of the virus."

"Chaos and inefficiency"

Brexit Plan Breaks UK

Philip Stephens

Brexit has made Scottish independence inevitable.
Government legislation to create a new UK single market across England, Scotland, Wales, and Northern Ireland shows contempt for the UK constitutional settlement. The Anglo-Scottish union of 1707 was a contingent agreement. Boris Johnson's claim that there is no border between the two nations shows ignorance.
Brexit can be the occasion for a new settlement between the four constituent parts of the union. Powers reclaimed from Brussels can be distributed to every corner of the UK. Johnson declares in public that he is a unionist, but privately he says Scotland spends money raised from English taxpayers on lavish welfare.
The legislation now before parliament to create a UK single market would tighten England’s grip over the rest of the UK. Decisions on norms, laws, and standards hitherto shared with Brussels will belong solely to Westminster. Powers held by the Scottish parliament and Northern Ireland and Welsh assemblies will be diluted.

Planar Graph Algorithm

Quanta

A new algorithm for determining when you can add edges to a graph so that it remains planar is exponentially faster than the previous algorithm from 1996.
Graphs are sets of nodes connected by edges. They can be used to represent everything from a social network to road systems to the electrical connections on a circuit board. If the graph is not planar, two roads or wires cross each other.
The 1996 algorithm runtime was proportional to the square root of the number of nodes in the graph. The new algorithm runtime is proportional to the cube of the logarithm of the number of nodes in the graph — an exponential improvement.
The same planar graph can be drawn in many ways. By showing that a flip that helps you add a new edge also makes the graph a better drawing, the new algorithm puts a backstop on the number of flips you may need to add an edge.
The new algorithm performs flips one at a time, searching for a solution. Either the algorithm finds a way to insert the desired edge, or the next flip undoes the previous flip, at which point you know you cannot add the edge.
Its runtime approaches the lower bound for this kind of problem. In real-world applications, graphs are usually simple enough to check by brute force.

Posh men are slightly scared of sex and learn early to treat it like a bloody good laugh. Ridiculing sex, making it less terrifying, is also why poshos love a slang word for it. When I worked at Tatler, we wrote pieces on the etiquette of the threesome, posh girls with whips, spanking, and telling dog toys from sex toys. Toffs often treat the act itself as a field sport, just like shooting. Both can be done outside. Both can be done in wellies. Both are often frightfully messy, but you clear up afterwards with a jolly hot bath.

AR For more nuance on sex, read Martin Amis.

Trump vs Science

Stephen Collinson

Donald Trump again ditched research and data on multiple fronts Monday with America under assault from concurrent crises.
His spinners are trying to cook the facts on the pandemic, which has claimed almost 200,000 Americans partly as a result. Trump continues to flout epidemiological guidelines by cramming people into indoor events that risked spreading Covid-19.
The president harbors bizarre theories on health, the environment, and other issues. He has turned away from science and expertise.
Trump visited California for a briefing on the fires that have consumed more than 3 million acres in a record year and have also ravaged other Western states. He said a failure to rake forest floors was responsible for creating tinderbox conditions.
Scientists say longer dry seasons and warmer weather are worsening forest fires. A local official told Trump it was time to take "our head out of the sand" by relying on the forest management excuse.
Trump: "It'll start getting cooler. You just watch."
Official: "I wish science agreed with you."
Trump: "I don't think science knows, actually."

AR We don't think Trump knows.

 

The Coronavirus Pandemic

Bill Gates

I warned that we were not prepared for the next pandemic. Our foundation can help fund scientists, but we cannot solve all the world's health problems.
Diagnostics were very poorly orchestrated in the United States. We should never have paid for test results that took longer than 24 hours. We should ensure that tests are available in the poorer areas of a city and not just for wealthier patients. The US response is much worse than it should have been, and the political leadership is responsible for this.
If this presidential election goes one way, the US will stay in the WHO and continue to pay its contributions without interruption. If the choice goes the other way, I still hope to convince the government that the money for WHO is well spent, even by the selfish yardstick of America First.
Aside from the US government, our foundation is the largest investor in vaccines. We invest billions and billions of dollars in development.

Ed Miliband Humiliates Boris Johnson

John Crace

The House of Commons debated the Brexit withdrawal bill last night. Former Labour leader Ed Miliband ripped into Boris Johnson and left him hopelessly exposed.
Johnson opened the debate in person. The EU wasn't negotiating in good faith. It was trying to blockade clotted cream being imported to Northern Ireland from Devon. No British parliament could possibly sign up to this.
Former attorney general Jeremy Wright challenged Boris on the ministerial code of breaking international law. Johnson said his attorney general had reckoned that the government could do anything Boris wanted it to. Wright just shook his head.
Miliband goaded the prime minister for his failure to understand Northern Ireland protocol and asked how he expected other countries to take us at our word if we broke international treaties. At first Boris merely rolled his eyes, willing Ed to disappear, but by the end there was nothing but cold fury in his stares.
Miliband delivered his arguments with the panache of a man who knew he had right on his side: "Come on, I know you're a details man. Show me the blockade. I will give way to you."
Boris remained almost immobile, the blood draining from his face, busted. He sneaked out of the chamber shortly after his evisceration, humiliated.

AR Thanks to mad UK rules, Boris still won the vote on his bill by 77 votes.

 

The Romantics and Us

Melanie Phillips

Sir Simon Schama says the preoccupations of our modern era, such as equality, sexual licence, or veneration of the natural world, go back to the Romantic movement of the late 18th and early 19th centuries. This was a revolt against convention and authority, elevating the rights of the individual and downplaying reason in favour of emotion and sensibility.
The Romantics belief the world could be remade through creativity and passionate emotion. Beauty was associated with generous behaviour, poetry with moral truth. The 1830 painting by Eugène Delacroix, Liberty leading the people, became the poster symbol of the 1968 student uprising in Paris.
Romantic idealism articulates feelings we all most deeply share. The imagination is a potent source of human sympathy, and Romanticism seems generous and inclusive. But often, the dreamers betray us all.
In the British Enlightenment, compassion was a social virtue. In France, the Enlightenment was not so benevolent. And the German Romantic movement developed both communism and fascism.
Schama is a Romantic. His new TV series is a source of enchantment. The heart soars, even though the head may shake in sorrow.

AR Typically, Phillips has soured this review with snide praise for Britain over the nasty continentals. The German Enlightenment — Hegel and all that — was glorious.

 

Alien Life in the Clouds of Venus?

New Scientist

Astronomers looking at Venus using the James Clerk Maxwell Telescope in Hawaii and the Atacama Large Millimeter/submillimeter Array in Chile see signs of phosphine gas in the Venusian clouds.
The only way phosphine is made on Earth is in laboratories or by microbes. The researchers tested a variety of ways to produce phosphine on Venus but failed to account for the observed quantity.
The surface of Venus is hellish (740 K, 90 bar), but conditions are temperate (300 K, 1 bar) at 50−60 km above ground level, where the phosphine was found.
The researchers say phosphine on Venus should persist for less than 30 Gs before it is destroyed, so something must be continually replenishing it for it to exist in the observed concentrations.
We would like to sample the atmosphere and chemically analyze it. A couple of balloons have been sent to Venus, but this is a tough engineering challenge.

AR I think Venus is more promising than Mars for life.

UK Trade Deals

Financial Times

The new UK trade deal with Japan commits it to tougher restrictions on state aid than the ones it is currently offering the EU in the Brexit talks.
In the bilateral UK−Japan agreement announced in principle on Friday, London and Tokyo have agreed to replicate the restrictions on subsidies in the EU−Japan deal that went into effect last year.
The EU subsidy regime is the main sticking point in the EU-UK negotiations. The UK government faces a major contradiction.

 

Honour rests on keeping our word

Geoffrey Cox

When the Queen's minister gives his word, on her behalf, it should be axiomatic that he will keep it, even if the consequences are unpalatable. By doing so he pledges the faith, honour and credit of this nation and it diminishes the standing and reputation of Britain in the world if it should be seen to be otherwise.
No British minister should solemnly undertake to observe treaty obligations with his fingers crossed behind his back. The withdrawal agreement and its attendant Northern Ireland protocol represent treaty obligations of this country to which the government, in which I had the honour to serve as attorney general, gave its solemn and binding word. It is therefore obliged to accept all the ordinary and foreseeable consequences of the implementation of that agreement.
Those manifest consequences included the inevitable application of EU tariffs and customs procedures to certain goods entering Northern Ireland from Great Britain and of the EU's state aid regime to the province. There can be no doubt that these were the known, unpalatable but inescapable, implications of the agreement. They included a duty to interpret and execute both the agreement and the protocol in good faith.

 

Bodger and his gang of bovver boys

Andrew Rawnsley

Boris Johnson is ready to violate a treaty that he negotiated less than a year ago, made the centre of his election campaign last December, and then had the Commons rapidly ratify in January.
Margaret Thatcher would melt in horror that a government that calls itself Conservative is fighting for the right to use government subsidies to subvert the single market.
Dominic Cummings wants to direct government aid in support of tech ventures. He wants to splash taxpayers' money at any "moonshot" idea that launches off the top of his head.
A senior Tory: "The climate of fear in Whitehall that [Johnson and Cummings] have created means officials don't rush to warn them when they're about to make a mistake."

Irresponsible, Wrong, and Dangerous

John Major, Tony Blair

Last October, the UK concluded an international treaty with the EU for the terms of Brexit.
Last week, with the Brexit negotiations in disarray, the UK government published a bill that it openly admits is a violation of that treaty.
The government says breaking international law is necessary to save the Good Friday agreement. We disagree. If parliament passes this bill, the UK will end up before the European Court of Justice.
This way of negotiating is irresponsible, wrong, and dangerous. This latest ruse has spectacularly misfired.

A lamentable summer
The Observer

Boris Johnson has made himself the target of excoriating criticism from two former prime ministers.
His government's internal market bill allows ministers to unilaterally overturn parts of the EU withdrawal agreement, in contravention of international law.
The EU has threatened legal action if the government does not alter the bill by the end of the month. The UK threat undermines trust and reduces the chance of an agreement.
The apparent intention was to lay the blame with the EU if no deal is reached. It seems there is no principle Johnson will not trample over if it suits his political agenda.
The government is threatening to rip up the Good Friday agreement. Any other government would have pursued a Brexit that kept the UK aligned with the single market and customs union. Johnson is willing to play petty politics instead.
The consequences will be felt too in our relationship with the United States. There are also broader repercussions for Britain's international standing.
Britain is on the cusp of a second pandemic wave, and we have a charlatan as our prime minister.

AR Bodger has ruined Britain.

 

The Roots of Populism

Matthew Goodwin

This is the age of populism. The populists may have had a terrible crisis, with their poll ratings crashing in most democracies, but their lingering presence reminds us of a deep reservoir of disillusionment and despair.
David Goodhart says our societies elevate highly educated cognitive elites (the Heads) above manual workers (the Hands) and people who care for their families and fellow citizens (the Hearts).
Goodhart previously identified a conflict over values between the Somewheres, who cherish their ascribed identities (faith, flag, family) and the Anywheres, who cherish their achieved identities (degree, career, success).
Given the AI and robot revolution, cognitive elites no longer have the world to themselves. Bespoke design jobs led by Hands and jobs that require emotional intelligence led by Hearts will boom in the years ahead.
Populist rebellions were driven by the Hands and Hearts. Britain has seen one of the strongest backlashes against Heads, although the irony is that voters have turned to renegade Heads to lead the revolt.
For the first time in the postwar era, Heads are having to make room for Hands and Hearts, who want to stay rooted in their communities and to enjoy an improved social status.

AR The AIR revolution magnifies the real power of the Heads, so much so that they can indulge the demands of Hands and Hearts.

Calamity for Britain

Peter Oborne

Twenty years ago, Boris Johnson hired me as political correspondent at the Spectator magazine. He was a joy to work for, a fine editor, and a loyal colleague. He stood up for the rule of law, for the UK, for the international order, and for honest politics.
This week, prime minister Johnson has deliberately trashed Britain's reputation around the world. Never before has a cabinet minister stated in the Commons that he knew a course of action was unlawful, but that he was going ahead to do it anyway.
Here is my own attempt at reconciling the inspirational editor I worked for two decades ago with the dishonest lawbreaker in 10 Downing Street today.
Early last year, Johnson entered into a bargain with Michael Gove and Dominic Cummings. They would propel him to Downing Street, enabling him to realise his ambition to become prime minister. But Gove and Cummings are in power. This is their policy.
Johnson is scared. His government is a national disaster. He senses that history will damn him as one of Britain's worst prime ministers. The nation needs a sober leader at this grave and terrible time.

AR Dump Dom.

 

The Future Has Arrived

Peter Gleick

Too much of the western United States is on fire. The fires are earlier, bigger, and hotter than usual.
We are reaping the consequences of more than a century of using the atmosphere as a dumping ground for carbon dioxide. For more than half a century, scientists have been warning of the growing threat of climate change.
The future has arrived. What we see now, with massive wildfires, worsening storms, unprecedented heat, and record droughts and floods is just the beginning of the climate changes to come. On top of rising oceans, the accelerating destruction of the Arctic ice cap, expanding water crises, and new health disasters, these climate impacts are something no human society has ever experienced. We remain woefully unprepared.
The influence of climate change on wildfires is easy to see. Global warming is diminishing our mountain snowpack, leading to hotter and drier summers. Severe droughts over the past decade have killed hundreds of millions of trees in our forests, adding to the fuels available to burn. Higher temperatures further dry out forest and rangeland soils.
The wildfire signal of climate change is being seen around the world, in southern Europe, Canada, Australia, South America, and Africa. Other climate-change impacts are accelerating too, in the form of storms, melting glaciers, rising seas, and more.
It is time for our politicians to lead or get out of the way. There is no time to waste.

EU Warns UK

Financial Times

EU officials told the UK on Thursday to immediately scrap its plans to override the Brexit treaty or face legal action.
The European Commission gave the UK government a deadline of the end of September to withdraw its planned internal market bill, warning that it threatened the Good Friday Agreement and "seriously damaged trust" between the EU and the UK.
EU diplomats say they have no intention of immediately shutting down the trade talks, as this would fall into a trap set by the UK. A diplomat: "If the UK wants a no-deal, it should just say so. We are working calmly and patiently towards a deal."
Former Tory party leader Michael Howard joined former prime ministers John Major and Theresa May in accusing the government of tarnishing Britain's international reputation.
EU options include hauling the UK before the European Court of Justice or launching an arbitration process.

Universal Emptiness

Charlie Wood

The modern universe looks too dilute.
On its way to Earth, light from a distant galaxy passes lumps of dark matter and clouds of gas. These bend the light gravitationally and kink the path of light reaching us. We can map statistical distortions in the shapes of huge numbers of distant galaxies across the sky.
The Kilo-Degree Survey (KiDS) observed millions of galaxies up to 100 Ym away. Calculated average distributions of hidden gas and dark matter showed clumps almost 10% thinner than the ΛCDM forecast. Multiple surveys using different techniques find similar results.

Trump Misled America

David Smith

Bob Woodward conducted 18 interviews with Donald Trump between December 2019 and July 2020 to write his new book Rage.
On January 28, US national security adviser Robert O'Brien warned Trump that Covid-19 would be the biggest national security threat of his presidency.
On February 7, Trump told Woodward: "It goes through the air. That's always tougher than the touch. You don't have to touch things .. you just breathe the air and that's how it's passed. And so that's a very tricky one .. This is deadly stuff."
On March 19, Trump told Woodward: "I wanted to always play it down. I still like playing it down, because I don't want to create a panic."
On April 3, Trump said at the White House: "I said it's going away and it is going away."
On April 5, he told Woodward: "It's a horrible thing. It's unbelievable."
In May, Woodward asked Trump if he remembered O'Brien's warning in January. He replied: "No, I don't, I'm sure if he said it — you know, I'm sure he said it. Nice guy."
In July, Trump told Woodward: "The virus has nothing to do with me. It's not my fault. It's .. China let the damn virus out."
Trump dismisses the book as "just another political hit job" and adds: "We wanna show confidence, we wanna show strength as a nation, and that's what I've done. And we've done very well from any standard."
America has the highest Covid caseload (6.35 million infections) and highest death toll (over 190,000) in the world. It also has one of the highest fatality rates per 100,000 population, at 58.

The Nuclear Threat

Jessica T. Mathews

In the early 1960s, USAF Strategic Air Command was asked how many Russians, Chinese, and Eastern Europeans would die from its nuclear war plan. The answer was 275 million, just from the blasts.
The United States and the Soviet Union each accumulated more than 30,000 nuclear weapons during the Cold War. Since then, the deployed US and Russian nuclear arsenals have been cut by nearly 90%, but we are not safer today.
China is now aggressively modernizing and enlarging its small nuclear arsenal. Russia and the United States are modernizing their arsenals with entire menus of new weapons. And there is deep and growing distrust among the great powers.
There are no metrics to measure what makes a deterrent credible. For the case that deterrence fails, making weapons and plans for every situation may be misunderstood as preparing an attack. Reasons to think that planning for limited nuclear war is fantasy emerge from any study of history, of how humans act under pressure, or of government.
At a disastrous briefing for Donald Trump in the summer of 2017 in the Pentagon, he was shown a chart illustrating US and Russian success in cutting their arsenals from more than 30,000 warheads to about 6,000 each. Why aren't we building back up to 30,000, Trump demanded in a tantrum. Modernizing the entire strategic nuclear force is now his top priority. The estimated price tag over the coming 25 years is $1.7 trillion.
The Trump administration has announced it will withdraw from the INF Treaty. The only remaining limit on strategic arms is New START, which expires in early 2021 unless extended by mutual agreement. The treaty limits each side to 1,550 deployed strategic warheads and 700 launchers.
Trump seems eager for a new arms race. US arms control negotiator Marshall Billingslea: "We know how to win these races, and we know how to spend the adversary into oblivion."

European Reshoring

Franck Riester

A Brexit deal remains unattainable so long as the UK remains unwilling to be bound by rules that would ensure a level playing field in trade with the EU.
We in France will try to stay calm and serene but firmly behind the line of the EU27. A compromise can come into play, but it is unattainable until the UK moves on the essential matter, which is the ability to ensure that trade is fair.
Europe needs to ensure respect for a certain number of principles such as reciprocity, the fight against global warming, mobilising for biodiversity, and so on. I think the coronavirus crisis has accelerated the awareness in public opinion and among different leaders.
Reshoring production of certain items is not about making everything in Europe or saying we will never again import raw materials, products, or services. It's about ensuring that we are self-sufficient in certain sectors or for certain products that seem essential.
The EU needs to look at those strategic sectors in which we should have some sort of autonomy in Europe. Globalization must not be detrimental to certain common goods: biodiversity, climate, child protection, the things essential to the world we live in.
We are reshoring and fighting for European sovereignty. But we want to keep the spirit of winning and expanding internationally.

Young people are told they are "consumers" in a shop where they can choose what and when to learn. They can expect a "service" and can take their university to court if their course did not "deliver" promised results. This is no longer a viable, decent learning environment.

Neuromorphic Computing

Danijela Marković et al.

Neuromorphic computing takes inspiration from the brain to create energy-efficient hardware for sophisticated information processing. Systems built with standard electronics achieve gains in speed and energy by mimicking the distributed topology of the brain. Scaling up such systems and improving their energy usage, speed, and performance by several orders of magnitude requires a revolution in hardware.
Including more physics in the algorithms and using nanoscale materials for data processing could have a major impact in neuromorphic computing. Results that leverage physics to enhance the computing capabilities of artificial neural networks include using resistive switching materials, photonics, and spintronics. These approaches could lead to low-power, miniaturized chips that infer and learn in real time.

Outlaw Government

BBC News, 1547 UTC

UK government Northern Ireland secretary Brandon Lewis told the Commons: "Yes, this does break international law in a very specific and limited way. We're taking the powers to disapply the EU law."

"A new ace up Britain's sleeve"
Marina Hyde

This is yet another crunch week in the Brexit we apparently got done eight months ago. But the government is now affecting not to understand the Brexit deal it has already signed and will seek to override it.
According to the Daily Telegraph, "Brexit deal never made sense," said the prime minister who negotiated it, then made his "oven-ready" Brexit deal the centrepiece of his election campaign.
UK Brexit negotiator David Frost cites his inspiration as Charles de Gaulle: "[He] always behaved as if his country was a great country even when it seemed to have fallen very low, and thus made it become a great country yet again."
But Britain is not behaving like a great power, despite the Daily Express describing some nonsense wheeze as a "new ace up Britain's sleeve" — a metaphor that simply confirms the UK is a country that cheats at cards.
The best you could say is that Britain is behaving like Donald Trump. Lying, reneging, then lying about the lies you told leave people believing there are no objective facts and all news is fake.

British Brexit Brinkmanship

Financial Times

Boris Johnson's government plans to publish a bill to nullify the legal force of parts of the withdrawal agreement already signed with the EU that Brexiteers say stops the UK reclaiming its sovereignty. But even as a mere tactic to break the deadlock in talks, the thinking here is flawed.
The gambit suggests that bluster and bluff lay behind signing the withdrawal agreement last year. The hardball tactics may be aimed at providing cover for later backroom concessions by the government. Yet every hint from a London official that compliance with UK commitments to the EU is optional has only increased resolve in Brussels to make them legally binding.
Brandishing the nuclear option of failing to comply fully with the withdrawal deal risks triggering the collapse of the talks. While the government may feel the economic damage of a no-deal Brexit is easier to hide in the midst of a global pandemic, the harm to the UK will not be lessened. A sudden rupture with its biggest trading partner during its deepest recession for decades would magnify the harm of coronavirus.
One thing worse than a no-deal Brexit would be one where Britain also calls into question its readiness to abide by treaties. Johnson is playing with fire.

The Tyrant Clown

Robert McCrum

My long affair with America, as an idea as much as a reality, began in the bicentennial year, 1976. Today, I lament the end of a long love affair.
I first felt it when, visiting New York in 2017, I attended a production of Shakespeare's Julius Caesar in Central Park. From the moment a strawberry blond Caesar in a MAGA baseball cap bounded on stage in a white shirt and a long red tie, this was a polemic on the leadership of an orange monster, half-clown, half-tyrant.
Like many US admirers, I've argued that America is not broken. But my admiration for the United States choked and died this year, bludgeoned by the racism, cruelty, corruption, and outright stupidity of the current administration.
Part of America's appeal, as a democratic experiment, is its Anglo-Saxon pragmatism, its willingness always to frame its radicalism as provisional, a work in progress. Such drive is exhilarating. Its audacity remains the age of reason's best assertion of human ambition.
The American ferment of ideas is noisy, messy, and occasionally violent. The tree of liberty was watered by the blood of patriots. But America's fundamental humanity was an inspiration.
Now it feels as if the well of US independence has been poisoned. Where language once provided a narrative line, now we find hate-filled presidential tweets. Ideas used to be a basis for community, now they only sponsor a raucous shouting match.
For the whole world, this is a democratic emergency. America was always a shining ideal, a society engaged in moral choices about improving the way people live. Today, that light has gone out.
We, once faithful supporters, have lost our appetite for the American ideal. When we contemplate the imminent battle, we feel dismay.

Germany Does Things Better

John Kampfner

In January 2021, Germany will be 150 years old. The country has developed a maturity that few others can match, and it has done so the hard way.
Coronavirus provided the ultimate test of leadership. Angela Merkel rose to the challenge. She told Germans in precise detail the sacrifices they would have to make and the emergency laws her government would have to impose. She never boasted.
Britain provided a case study of how not to deal with a crisis. The bombast of Boris Johnson was in inverse proportion to his government's competence. With a mixture of libertarianism and English exceptionalism, the prime minister declared that Britain would get through it.
The UK has had the highest death toll in Europe. This tragedy followed Brexit. Germans watched in horror as a country they admired for its pragmatism fell into pseudo-Churchillian self-delusion.
The beautiful border city of Aachen tells the German and European story in microcosm. This was the front line where the Germans sent troops into Flanders in 1914 and where American tanks crossed the Siegfried Line in 1944. Under Allied control, the city became a test bed for postwar democratic reconstruction.
Aachen is the centre of Europe, the cradle of Western European culture. It is synonymous with Charlemagne, who brought most of Europe under his wing. In 1806, when Napoleon invaded the city, he declared: "Je suis Charlemagne."
The city made its first annual Charlemagne award in 1950. Among the Charlemagne laureates are Jean Monnet, Konrad Adenauer, Winston Churchill, Robert Schuman, Edward Heath, Roy Jenkins, Tony Blair, Jean-Claude Juncker, Angela Merkel, Donald Tusk, and Emmanuel Macron.

Brexit: "We won't blink"

Lord Frost

We want to be able to control our own laws and do things our way.
We are not going to be a client state. We are not going to compromise on the fundamentals of having control over our own laws. We are not going to accept level playing field provisions that lock us in to the way the EU do things. We are not going to accept provisions that give them control over our money or the way we can organise things here in the UK.
That's what being an independent country is about, that's what the British people voted for, and that's what will happen at the end of the year, come what may.
What we want is the restoration of our own sovereignty and freedom as a country. This happens whether the EU likes it or not at the end of the year.
We are not going to agree to any arrangement that leaves the EU with some say over what we do with our money. We're not going to accept that sort of control because that wasn't what Brexit was about.
We want to get back the powers to control our borders. If we can reach an agreement that regulates trade like Canada's, great. If we can't, it will be an Australian-like trading agreement. We are fully ready for that.

The Brexit Election

David Graeber

The 2019 general election in the UK was a victory for older voters. Swing voters broke right, not left.
In the Labour party, Blairites had defined the pragmatic center of British politics, where the UK economy would continue to be driven by finance, construction, and real estate. The result was that almost everyone spent more time filling out forms. The UK is now home to almost half a million accountants and lawyers.
Jeremy Corbyn was elected as Labour leader to turn the party back into a social movement. Young people began to join Constituency Labour Parties (CLPs) to move to grassroots democracy. For them, the real issues were austerity, wages, health, education, and public services.
For most in the Parliamentary Labour Party (PLP), these developments caused alarm. They found themselves so out of step with their CLPs that they saw any effort to democratize the internal workings of the party as a threat.
Ever since the economic crash of 2008, the left had tried to make villains of the bankers. Yet this approach gained little traction. The right instead tried to make villains of the bureaucrats.
Around the globe, developed economies have seen a huge growth (1) of clerical, administrative, and supervisory work, and (2) of care work: medical, educational, maintenance, social care, and so on. Productivity in the caring sector has decreased, largely due to the growing number of administrators. This decline has squeezed wages.
A global revolt of the caring classes benefited not the left but the right. Formerly leftist parties from the United States to Japan had rebranded themselves to represent the new middle classes. They learned to see society, democracy, and rule of law less as a web of human relationships than as a set of rules and institutional procedures.
For most caregivers, administrators are the enemy. If you are a nurse, they are your real class antagonist. The managers not only get big salaries but also hire useless flunkies who then create endless reams of new paperwork.
Labour incorporates both the teachers and the school administrators, both the nurses and their managers. The party finds it hard to speak for the revolt of the caring classes.
The new populists present themselves as the precise opposite of the infuriating administrator whose rules, meetings, paperwork, and seminars make it impossible for you to do your job. Brexit politics pushed Labour into defending administrators.
The Leave campaign took aim at immigration and at distant and uncaring Brussels bureaucrats. Leavers argued that Remainers in Whitehall were using every sort of procedural trick in the book to thwart the popular will.
The UK rejected centrism. It now has a hard-right government with no idea how to translate Brexit into economic prosperity. Boris Johnson may be remembered as one of the most disastrous prime ministers in British history.

The Trump Malignancy

Jonathan Freedland

Donald Trump reportedly described US troops who died for their country as "losers" and "suckers" and demanded that a military parade exclude wounded veterans.
Close to 200,000 Americans are dead thanks to a pandemic that Trump refused to admit was happening. The US economy lies in tatters, racked by mass unemployment.
This week, Trump urged his supporters to vote early by mail-in ballot and then turn up in person on election day to vote again. He was urging them to break the law.
Earlier, Trump said postal voting was bound to lead to "the most INACCURATE & FRAUDULENT election in history" and suggested delaying the election.
Trump has installed a head of the US Postal Service who is gutting its ability to process mail-in ballots in time. And he's starving the service of cash.
Trump: "If they don't get those two items, that means you can't have universal mail-in voting because they're not equipped to have it."
The choice in the November 3 election is between democracy and autocracy.

AR QAnon: Where We Go One We Go All

 

Red Pill

Michael Gorra

The narrator of Hari Kunzru's sixth novel is a Brooklyn academic who has a nameless dread that "something profoundly but subtly wrong" is about to happen in the world. He is offered a fellowship at a Berlin think tank.
The think tank is on the Wannsee and looks across the water to the villa where the Nazis planned the Holocaust. The narrator quickly begins to see the study center as oppressive. When he makes a stand, he is ordered to leave immediately.
Just before leaving Berlin, the narrator meets Anton, who says those who can't take the truth about human life are squeamish. The narrator later stalks Anton on the web, into a territory of alt-right message boards and conspiracy theorists.
Kunzru is a shrewd observer of recent politics, as when the narrator lets one of the villa's cleaning staff, a former East German punk rocker, describe her experience of Stasi persecution.
Red Pill ends in November 2016.

AR I think I'll hold fire on this one.

Higher Category Theory

Emily Riehl

Editorial Introduction
In 1945, Samuel Eilenberg and Saunders Mac Lane proposed that mathematics needed to replace the notion of equality with the deeper idea of equivalence. They developed new mathematical structures that captured the many ways two things might be equivalent.
In higher category theory, mathematicians also think about equivalences between equivalences, and equivalences between equivalences between equivalences, and so on upward in an infinity category.
Emily Riehl and Dominic Verity are nearly finished writing a book on the foundations of infinity categories in mathematics.

ER When I was an undergraduate, I was really attracted to abstract algebra. I found the proofs really satisfying. I had the sense that the abstract things are somehow clearer to me than the more concrete things, because I was just more confident that I was understanding them correctly. Category theory is like that to the nth degree.
Over time, mathematicians have developed an increasingly flexible view of what it means for two objects to be the same. Two objects in a higher category should be considered the same when they are equivalent, which means seen as the same by all other objects in the higher category.
This book describes results from papers I've written together with Dominic Verity starting in 2012. We've been developing a new approach to the foundations of infinity category theory. Those foundations were developed by André Joyal and independently by Jacob Lurie.
Dom and I feel like our perspective is mature enough to rewrite the theorems in a more accessible form directed at somebody who's learning this stuff for the first time. We're trying to give a user-friendly rewrite of Lurie. The theorems are the same, but I think the new proofs are better.

AR I found Lurie's work too daunting. Perhaps Riehl and Verity can help me out.

IIEA Keynote Address

Michel Barnier

We are now less than four months away from 1 January 2021. This is the date chosen by the UK for its economic and commercial Brexit, after the political Brexit in January 2020.
We have three major tasks for this year:
1 Negotiating our future partnership
I am worried and disappointed by the UK's lack of engagement on three points:
1.1 Since the start of these negotiations, the UK has refused to engage on credible guarantees for open and fair competition. A level playing field is the only way to start a new relationship between the EU and the UK on a firm and sustainable footing.
1.2 The UK has not shown any willingness to seek compromises on fisheries. The UK would lock out the fishermen of many countries from waters they fished in long before 1973. That is not acceptable. Without a solution on fisheries, there will be no new economic partnership with the UK.
1.3 The UK has been extremely reluctant to include any meaningful dispute settlement mechanisms in our future agreement.
On all these issues, we are simply asking to translate the political engagements taken in the Political Declaration into a legal text. Yet, on all these issues, the UK side continues to disappoint.
2 Implementing the Withdrawal Agreement
Before the end of the year, we need to ensure the full and effective implementation of the Withdrawal Agreement. This is the only way to avoid a hard border on the island of Ireland and preserve the all-island economy, it is the only way to preserve the integrity of the Single Market and all its guarantees, and it is a precondition for the EU and the UK to be able to forge a meaningful partnership built on trust.
3 Getting ready for changes at the end of the transition
On 1 January 2021, the UK will leave the Single Market, the Customs Union, all EU policies, and all of our international agreements. No trade agreement can change this.

AR This is tragic. Damn Bodger.

 

Bodger Flubs Again

John Crace

Boris Johnson is failing at being prime minister. In this week's Prime Minister's Questions session, Sir Keir Starmer asked a straight question on the exam chaos, but Boris resorted to bullshit and bluster in reply. Starmer is the one who looks fit to run the country.

PMQs 2020-09-02
Hansard

KS: Let me start today with the exam fiasco .. We learned yesterday that the education secretary knew well in advance that there was a problem with the algorithm .. When did the [PM] first know that there was a problem with the algorithm?
BJ As a result of what we learned about the tests .. we did act.
KS Let me ask again: when did the [PM] first know that there would be a problem with the algorithm?
BJ Ofqual made it absolutely clear .. All summer long, he has been going around undermining confidence and spreading doubts .. the parents, pupils, and teachers in this country are .. going back to school in record numbers, in spite of all the gloom and dubitation that he tried to spread.
KS The [PM] is just .. playing games .. fooling nobody. Even his own MPs have run out of patience .. [One] of his MPs .. said: "It's mess after mess, U-turn after U-turn .. It's a fundamental issue of competence, God knows what is going on. There's no grip." His own MPs are right, aren't they?
BJ This is a leader of the opposition who backed remaining in the EU and now is totally silent on the subject. Now he has performed a U-turn .. This is a leader of the opposition who supported an IRA-condoning politician who wanted to get out of NATO and now says absolutely nothing about it.
KS  I worked in Northern Ireland for five years with the police service of Northern Ireland, bringing peace .. I ask the [PM] to have the decency to withdraw that comment .. [T]he next major decision for the [PM] is on the furlough scheme .. will he act now?
BJ We are .. getting our pupils back to school .. and we are getting people back to work. What he wants to do is extend the furlough scheme .. we would rather .. get people into work.
KS I asked him to do the decent thing but doing the decent thing and this [PM] don't go together. This has been a wasted summer. The government .. have lurched from crisis to crisis, U-turn to U-turn .. [with] 12 U-turns and rising, the only conclusion is serial incompetence.

Dodecahedron News

Erica Klarreich

A trio of mathematicians has resolved a basic question about the dodecahedron: Suppose you stand at one of the corners of a Platonic solid. Is there a straight path you can take to return you to your starting point without passing through another corner?
For the cube, tetrahedron, octahedron, and icosahedron, the answer is no. For the dodecahedron, Jayadev Athreya, David Aulicino, and Patrick Hooper have shown there is an infinite number of such paths. Their solution required modern techniques and computer algorithms.
To understand straight paths on a Platonic solid, start by cutting open enough edges to make the solid lie flat, forming a net.
Flatten out the dodecahedron, walk along this flat shape, hit the edge of the net, hop to a different pentagon, and rotate by some multiple of π/5.
Alternatively, when we hit an edge of the net, glue on a rotated copy of the net, continue straight on, and add a new net whenever we reach the edge of our world.
When we have traveled through 10 nets, the next net we add has the same orientation as the first, related to it by a translation. We can glue the edge of the 10th net to the corresponding parallel edge in the original net. Gluing all such corresponding edges gives us a translation surface.
The translation surface is a representation of the dodecahedron with 10 copies of each pentagon and shaped like a torus with 81 holes. It also represents a double pentagon made by attaching 2 pentagons along a single edge and then gluing together parallel sides to create a torus with 2 holes and a rich collection of symmetries.
The trio used the symmetries to classify all the straight closed paths through a corner on a dodecahedron.

AR Wow — we can still say something new about the dodecahedron.

A Global Hit

Tom Whipple

Several billion tons of plasma, thrown off by the Sun, whizzed past Earth in September 1859. The Carrington Event is now referenced on national risk registers. In 2015, the risk of solar storms was considered by the UK government committee SAGE.
University College London professor of disasters and health Ilan Kelman: "The possible consequences are immense. Anything which is not shielded, anything which cannot deal with sudden current fluctuations, could be damaged and potentially put out of service .. There could be trillions of pounds of immediate damage."
Solar storms happen regularly. Humans survive them just fine, but our electronic infrastructure is in jeopardy. Small solar storms have knocked out major grid transformers.
When the Sun blasts out a great glob of magnetic plasma, it does so asymmetrically. Coronal mass ejections spring out from the rotating Sun on a fixed trajectory. In 1859, a glob hit us square on. In 2012, we watched a similar eruption whizz past harmlessly.
First to arrive are the X-rays. They reach us in 8 minutes and interrupt HF communications. An hour later come the charged particles. They leave a trail of destruction among orbiting satellites and produce auroras in the upper atmosphere. Days later, the coronal mass ejection arrives.
Professor Kelman: "What are we going to be doing in that time? If we suddenly had three days' notice that all of the information and communication technologies are going to go down — that credit cards, debit cards, ATM machines, mobile phones are going to go down, what happens?"
Heads, the magnetic field of the plasma is oriented in the same direction as the Earth's and passes harmlessly by. Tails, it's not. Then the coronal mass ejection will hit and cause a catastrophic surge in power grids worldwide. The UK National Grid has a plan to reboot after a failure. The US grid is more vulnerable.

AR This is not the Sunfall scenario, but it's related.

 

Brain Implants

Moises Velasquez-Manoff

We are at the dawn of a new era where people control intelligent machines merely by thinking.
We can already use machine learning to read what a subject is viewing. A team showed volunteers in fMRI machines movie clips. By matching brain activation and images, an AI built a model of how the visual cortex worked. As the volunteers were shown movie clips, the model visualized what it thought they might be looking at. The patterns of brain activity were translated into moving images.
Advances in technology at the interface of flesh and machine are important, but the AI matters more. Trying to understand the brain from outside the skull is hard. A thinking cap needs to know what's happening in the nearly 100 billion neurons in the brain.
Implanted sensor arrays can let paralyzed patients move robotic arms or cursors on a screen just by thinking. The next step is to let them move a paralyzed arm or hand and regain sensation. A man paralyzed from the chest down had sensory information from a robotic arm into the part of his cortex for his hand and learned to feel a robotic hand as his own.
Neuralink is a brain-sensing tech that requires surgery, but it's thin, flexible, and can adjust to the hilly topography of the brain. It has hairlike filaments that sink into brain tissue. Each filament contains multiple sensors, allowing the capture of more data than flatter arrays on the brain surface. It can both read and write to the brain, and a robot assists with the implantation.
Nanotech sensors may be small enough to avoid an immune reaction. Neural dust could be powered by beams of microwaves or ultrasound from outside the skull. Smartphones could process data from chips and sensors around the body. Glasses and earbuds could give us a web interface.
One technology that can read and write to the brain uses genetic engineering. First, mice are infected with a virus that inserts two genes into their neurons. One prompts the cells to produce a protein that make them sensitive to infrared light; the other makes the neurons emit light when they activate. When the neurons fire, we see them light up and activate them with an infrared laser. We can both read the mouse brain and write to it and manipulate the mouse like a puppet.
Such brain technologies are fast approaching. We need to be prepared for them.

AR I predicted this in 2010.

 

Automating Math

Stephen Ornes

Set theorist Paul Cohen once predicted that all of mathematics could be automated. Computers are useful for big calculations, but proofs often require complicated creative thinking. Can a system generate an interesting conjecture and prove it in a way that people understand?
Fields medalist Timothy Gowers sees theorem provers replacing human referees at major journals. They offer a way to keep the field honest by checking proofs. They can also be useful teaching tools in computer science and mathematics.
A group at Google Research sees the challenge of automating proofs as a subset of natural language processing. The group wants to capitalize on recent advances in language recognition to use neural networks to generate new proofs. The neural net could learn to understand what a proof looks like.
No one knows whether these efforts will fulfill Cohen's prophecy. Gowers predicts mathematicians will enjoy a kind of golden age, when mathematicians do all the fun parts and computers do all the boring parts: "But I think it will last a very short time."

AR I predicted this in 1989.
